Download the v7 folding client and install it using the recommended defaults. If you're new to folding, input your TPU username as your folding name and input team 50711. Leave the passkey field blank as we will cover a method of assigning a passkey to each folding slot later.

Step 2:

You'll need to add a beta flag on each nVidia GPU. In v7, switch to expert mode:

Insert client-type in name field and beta in value field as shown below.
Insert passkey in name field and "your actual alphanumerical passkey in value field as shown below.
In Click Ok - Click Ok - and Save.

Step 4:

Quit the folding client and restart it. In post 2 we will cover how to replace beta folding core version 2.25 with 2.22 to increase your GPU PPD by nearly 30% or better for Fermi cards only.

Open the directory in which the core is located as shown here, but replace my user name with your user name. You may need to manually type in the AppData folder if it's hidden or show hidden folders. The path to the file on my PC is: C:\Users\BWG\AppData\Roaming\FAHClient\cores\www.stanford.edu\~pande\Win32\AMD64\NVIDIA\Fermi\beta\Core_15.fah

Copy the core over and replace it. Right click each GPU slot and click fold. That's it.

Extra edit: The rig where the 450 nests was "moved to a farm and it is so happy". In other words it kept BSOD on me and was moved to my workshop for parting. Today I needed to use Putty (key-in for remote computing on my one cloud HP CPU since it stopped reporting) and it picked up an 8057 and finished it as well AND picked up one more so I give it one chance. Good dog (as long as you do 45k PPD)

Darn, okay, I need to wait a bit first:
Edit: bloody amazing, I can watch videos, surf and do pretty much anything I want
while folding. Never could do that before on the 2xx series cards.
Can't wait to see my 480 dump.....

Maybe it should be pointed out that the PPD increase won't happen right away.

In my case, I set the client up fresh on my GTX670 and I had to sucessfully complete 3 normal WUs first before I was assigned a beta WU.

I also had one of my GTX470s that was slighly unstable, and ended a WU early with Unstable_Machine. After making it stable, I had to wait for it to finish 3 normal WUs sucessfully before it got a Beta as well.

Of course if you've already been folding for a while, the PPD increase should happen much faster.
